Abstract
This study was conducted primarily to obtain factors affecting yield for forest plantation Eucalyptus spp in Aek Nauli, North Sumatera, Indonesia. The data in this study used 650 rhombic plots consisting of 106 PSPs and 544 inventory plots with several variations of plot size. Stands features referred to diameter, height, merchantable volume, age, species, spacing, site index, basal area, and density of Eucalyptus species. Geographical features referred to slope, elevation, rain fall and soil of the study area .The most important factors affecting yield of the E. hybrid, E. urophylla, and all Eucalyptus species are rainfall followed by soil group A while for E. grandis, E. pellita and mixed Eucalyptus are stand density, elevation, interaction site index and age, respectively.
